BYRON O. BRADLEY, OF BRADLEY, ILLINOIS, ASSIGNOR TO DAVID BRAD- LEY MANUFACTURING COMPANY, OF BRADLEY, ILLINOIS, A CORPORA- TION OF ILLINOIS.

HAY-PRESS- Specification of Letters Patent.

Patented Oct. 31, 1905.

T at whom it may concern:

ley, in the county of Kankakee and State of Illinois, have invented certain new and useful Improvements in Hay-Presses, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to hay-presses, and particularly to those operated by horsepower.

In the use of hay-presses it frequently happens that the ground where the press stands is not level, so that the front and rear wheel axles which support the machine are tilted slightly with reference to each other, consequently tilting the baling-chamber with reference to the operating mechanism in such a way as to cause the parts to bind to such an extent as to interfere With the proper operation of the machine.

One of the objects of my invention is to provide a construction by which due allowance is made for the unevenness of the ground, so that such tilting does not result in binding, and is consequently unobjectionable.

Another object is to provide means for preventing the cross-head by which the plunger is operated from slipping laterally off the end of the plunger-rod or pitman.

These objects I accomplish as illustrated in the drawings and as hereinafter described. VVhatI regard as new is set forth in the claims.

In the accompanying drawings, Figure 1 is a partial plan view of a hay-press embodying my improvements. Fig. 2 is a side elevation of the press shown in Fig. 1. Fig. 3 is a sectional view, and Fig. 4 is a partial plan view.

Referring to the drawings, 5 indicates the plunger-rod or pitman; 6, the plunger-head; 7 the frame in which the baling is done, and 8 the baling-chamber.

9 indicates the cross-head by which the plunger-rod is operated, said cross-head being mounted on a vertical pivot 10 and having rollers 11 12 at its'ends which engage a casting 13, carried at the adjacent end of the plunger-rod 5.

14 indicates the sweep to which the horses are connected and by which the cross-head 9 is rotated.

15 indicates a brace for the sweep 14, which is connected to the inner end of the sweep by a bar 16 and is suitably connected to the outer end of said sweep in the usual way.

As best shown in Figs. 1 and 2, the casting 13 is provided at one side with upper and lower flanges 17 18, respectively, which project over the rollers 11 12 when said rollers bear against the operating-face of said casting, as shown in Figs. 1 and 4. Said flanges therefore not only guide the rollers 11 12, but confine them so that they cannot move laterally out of engagement with said casting.

As best shown in Fig. 3, the plunger-head 6 is best mounted on rollers 19, which run on the lower surface of the frame 7 and support the plunger-head 6. Said plunger-head is provided with a rod or pin 20, which extends vertically therethrough and is arranged centrally thereof, as shown in Fig. 3, its ends being secured in the upper and lower plates 21 22, respectively, of the plunger-head. Said rod 20 passes through a sleeve 23, provided at the inner end of the plunger-rod 5, and serves as a means of connecting said plunger-rod with the plunger-head. As best shown in Fig. 3, the passage 24, through which the rod 20 passes, is narrower at the center than at the ends of said sleeve-that is to say, said passage flares from about the center toward the ends of the sleeve-so that said sleeve may rock with reference to the rod 20 to a limited extent. It will thus be seen that the plungerhead may be turned angularly slightly with reference to the plunger-rod. Consequently the rear axle, which carries the frame 7 and plunger-head, may be tilted with reference to the front axle, which carries the operating parts of the machine, without danger of cansing the plunger-head to bind in the frame 7, as is the case in prior constructions.

In Fig. 3 Ihave illustrated the rear wheels in dotted lines as standing in trenches dug to receive them, which arrangement is usually made so as to lower the plunger-rod 5 sufficiently to permit the horses to step over it in operating the press. Obviously in digging such trenches it is exceedingly difficult to level the axle, and consequently my improved arrangement by which the necessity of leveling the machine is avoided is highly advantageous.

I wish it to be understood that any equivalent construction for securing the operation described falls within the scope of my invention; but the construction shown is the best embodiment of the invention at present known to me.

That which I claim as my invention, and desire to secure by Letters Patent, is

1. In a hay-press, the combination of a plunger-head, a plunger-rod adapted to be reciprocated for operating said plunger-head, and a pivotal and angularly-movable connection between said plunger-rod and plungerhead, substantially as described.

2. In a hay-press, the combination of a frame, a plunger-head adapted to be reciprocated therein, a' plunger-rod, and means for connecting said plunger-rod with said plunger-head to permit of rocking said head and also rotating said head to a greater or less extent with reference to the plunger-rod, substantially as described.

3. In a hay-press the combination of a BYRON C. BRADLEY.
